Marsh plants are typically composed of leaves attached to a central stem. Both the leaves and the stem are flexible and contribute to wave attenuation. This study developed a model to predict wave damping within a marsh based on a simple representation of the wave-induced drag on an individual, flexible marsh plant. Specifically, the drag force on the leaves and the stem was represented separately using a scaling law developed for an isolated plant element, and a sheltering coefficient was applied to account for drag reduction on the leaves due to the interaction among the leaves and stem. The wave damping model was validated against laboratory experiments. The model was also compared to measurements of wave dissipation made in the field.

柔性沼泽植物的单波阻尼模型

沼泽植物通常由附着在中央茎上的叶子组成。叶子和茎都是柔韧的，有助于波衰减。本研究开发了一种模型，可根据对单个灵活沼泽植物的波浪诱导阻力的简单表示来预测沼泽内的波浪阻尼。具体来说，叶子和茎上的阻力分别使用为分离的植物元素开发的比例定律来表示，并应用遮蔽系数来解释由于叶子和茎之间的相互作用而导致的叶子上的阻力减少。波浪阻尼模型已根据实验室实验进行了验证。该模型还与现场进行的波浪耗散测量进行了比较。
